v To all whom/ it may concern:

Be it known that I, OSCAR M. BRYAN,

Chanute, in the county of Neosho and State of Kansas, have invented certain new and useful Improvements in Baling-Machines, of which the following is a specification.

This invention comprehends certain new and useful improvements in automatic machines for baling hay, the invention embodying means for automatically carrying the hay into the machine, for packing it down into" a baling chamber, for compressing it in said chamber, for encircling the bale with wire hoops, and for automatically carrying the bale, after completion, out of the baling chamber soas to permit it to be deposited to one side of the machine out of the way of the ground wheels, the different mechanisms being so timed that the baling operation will be practically a continuous one.

The machine is intended to travel over the fields after the hay has been mown, and is designed to be incorporated or embodied with a rake and an elevator or conveyer to carry the hay into the rear end, of the machine for engagement by a carriage that is arranged to move a predetermined quantity of hay forwardly in the machine over the baling chamber, into which it is then packed by vertically movable packing forks; but as the rake and elevator are classified as different inventions from the rest of the mechanism, they are not disclosed in the present application.

The invention has for its primary object an automatic hay baling machine embodying an improved construction and arrangement of carriage and actuating mechanism therefor, arranged to receive a quantity of hay that is fed up to the rear end of the machine by the elevating mechanism, and to carry the hay forwardly to a space in .the framework above the baling chamber, said mechanismincluding doors and improved tripping devices therefor, the doors being designed to fold inwardly at the rear.of the load of hay so as to constitute tuckers.

The invention has for a further object, a machine of this character embodying improved actuating mechanism for the packing forks that are designed to pack the hay down into the baling chamber after it has been brought to a point above the latter by the carriage above mentioned.

The invention also has for its object an improved construction of baling chamber embodying doors for the top of the chamber. These doors open when the beater or plunger arrives at the far end of the doors, so that the next feed of hay will come in over the plunger and the packing forks will begin to move down somewhat before the rebound of the plunger, it being understood that the plunger travels some little distance, say five or six inches, forward after the doors have been opened. This chamber also embodies improved locking devices for the doors, and improved latch releasing devices and door opening devices that are successively brought into operation, as will be hereinaftermore specifically described.

A further object of the invention is an improved construction and arrangement of beater or plunger and actuating device therefor, which will impart considerable power to the plunger in the forward movementthereof and permit the same to have a quick rebound, the plunger, in the preferred embodiment of the invention, being also designed to act as the specific means for releasing the latches that hold the doors closed at the top of the baling chamber while the hay is being compressed, and the plunger embodying an improved front end construction whereby all liability of the plunger sticking in its return movement is avoided.

The invention also has for an object an improved construction of baling chamber front end designed to retain the hay as against the forward pressure of the plunger, and improved means whereby the retaining device, part of which forms the front end or door of the baling chamber, will be quickly and automatically moved to an open or inoperative position as soon as the plunger has, completed its forward movement to produce the required amount of compression in the bale.

A further object of the invention is improved hoop-applying devices that are automatically operated to carry the bale hoops in front of a bale as it is belng formed, and finally swing the hoops around the rear end of the completedbale so as to hold the latbeater on its return movement and which is described, I shall notdescribe it specifically, except so far as is necessary in connection with some details of construction. It is supported upon front and rear ground or traveling wheels, the latter being relatively large, and designated by the reference numeral 1. These ground wheels, which are the main driving wheels 'of the machine, are both mounted on a transversely extending axle or shaft 2 (Fig. 15, Sheet 8) the wheels being loosely mounted on the spindle of said shaft and operatively engaging the shaft only in the forward movement of the machine, by pawls 3 engaging ratchets 4. This shaft 2 constitutes the main drive shaft for all of the mechanisms involved herein and carries near its ends perpendicularly or radially disposed sweeps, preferably rigidly connected thereto, each of said sweeps embodying two oppositely extending arms 5, each of which preferably carries a roller 6.-

The load delivering carriage and its actu? ating mechanism.'-Asthe hay is carried up" to the rear end of the machine and in be-j tween the main rear ground wheels 1, it is intended to be caught and grasped by hooks 7 that form part of a carriage 8, tothe sides of which are journaled traveling wheels 9- mounted in horizontally disposed longitudinally extendin uide channels 10, (see Figs. 1 to 4, inc usive, Sheets 1, 2 and .3), The carriage 8 operates above a horizontally disposed platform 11, the forwardjend of,

which terminates directly above the baling chamber hereinafter specified, and as -';the

carriage is moved forwardly, the hay dragged forwardly thereby. When the car riage is at the rear end of its movement, latwide open position back against the sides of the run-way of which the platform 11 forms a bottom, andas the carriage is moved forwardly, carrying the hay with it, spring lugs 13 that project downwardly from the carriage merely pass overrods 14 which, project out from the hinged ends ofthe doors 12; but in the return or rearward movement of the carriage 8, these spring lugs 13 engage the rods 14 so as to swing the doors inwardly'and forwardly to their relatively closed positions illustrated in Fig. 5, whereby the doors will serve as'tuckers to tuck the hay inwardly and forwardly from the sides of the run-way. In this return movement of the carriage 8, retaining arms 15, that have been held by frictional spring hinges 16 against any swinging movement in the forward. movement of the carriage, will ride over the top of the load of hay, as best illustrated in Fig. 3 and-will finally drop down behindthe load when the carriage has been returned to its initial rearward position. These movements are imparted to the carriage 8 by means of the sweep arms 5 hereinbefore mentioned and bar 20 to the rear end of which a friction disk 21 is journaled, whereby as the lever 18 is rocked by being struck with said arm 5,

'the bar '21 will be pulled' forwardly and the disk 21 will be caused to engage the periphcry of the wheel 1, effecting the rotation of the disk in a direction to wind up on a drum 22 (Sheet 7, 13) a cable 23 which is secured to the arm 17. It is, of course, to be I understood that these parts are duplicated on the opposite sides of the machine, as will be seen by reference to Figs. 4, 5, 6, 13 and 15, but are described singly, for the sake of clearness. The same will hold true of other parts ofthe mechanism to be hereinafter specified, in order that, wherever convenient, only one side of the machine need be considered. It is also to be understood that an appreciable interval will elapse between theforward and rearward movements of the while the packing forks, now to be described, are. operated to pack down into the baling chamber the hay that has been I brought up to the same bythe carriage. erally swinging tucking'doors 12 are in their.

Packing forks and their operating means.- The, forks themselves, designated 24, may be of anydesired construction or \type and are carried on zthe relatively free ends of support-ingarms 25 that are two in number in the present instance arranged in laterally spaced-parallel relation to each other extendin longitudinally of the machine and pivote at-thei-r forward ends on standards -26 to rockabont horizontal axes (see Figs. 1"and-13'Sheet 7 Intermediate of their ends, the supporting arms 25 are connected (to depending links 27, and said links are in turn connected at their lower ends to cranks 28 on relatively short transverse'shafts 29. These shafts are supported by pivoted standards 30 and are provided with friction disks 31, the. shafts being operatively connected to the bars 20 hereinbefore referred to in connection with the carriage operating mechanism, whereby as the sweep arms 5 revolve, there will come a time when they will strike levers 32 fulcrumed intermediate of their ends at 33 and connected at their upper ends to'the bars 20, and the consequent movement of said levers 32 will move the bars 20 in a direction to carry the disks 21 vided at its front end with a forwardly projecting bottom flange 60 and vertical side flanges 61 within which is a scraping blade dicated by dotted lines in Fig. 7, (Sheet 4),

so as to prevent any of the hay from catching in between the top of the plunger and the adjoining wall of the chamber.

The plunger operating mechanism embodies a relatively long pit-man 64, (see Sheet6) which is pivotally connected to the plunger near the front end and midway of the top and bottom of the latter by means of a transversely extending rod 65, the pitman extending downwardly and rearwardly, as shown, and being ivotally connected at its rear lower end to llIlk bars 66 which are pivoted in the framework at their upper ends at 67, converging downwardly, as best seen in Fig.'11, and braced by a cross rod 68. Links 69 are pivotally connected at their rear ends to the same pin or pivot bolt 70 which connects the link bars 66 with the pitman 64, the opposite ends of said link 69 having received between them and being pivotally connected to a laterally projecting lug 71 that is formed on one end of a slotted link 72. A clevis or shackle 73 carries a roller 74 mounted for movement in the slot of the link 72, said shackle being secured to the lower end of a cable7 5 which may be formed of strands or layers of steel wire or bands, as clearly illustrated on Sheet 6. The upper end of the cable 75 is connected to a cross bar 76 carried by a segment drum 77, said drum being freely swung upon the driving axle or shaft .2. Arms 78 are rigidly connected to the shaft 2 and project in opposite directions therefrom, said arms being mounted within the drum 77 and being designed, in the rotation of the shaft, to engage the cross bar 79 which is secured to an arched frame 80 pivotally connected to the drum and within the same and maintained in a definite position therein by-a spring brace 81.

As the shaft 2 rotates, one of the arms 78 will engage the cross bar 7 9 of the drum 77, the drum and shaft then turning together until the cross bar 79 is stripped from thearm by engaging a stationary stud 82 secured to some convenient portion of the frame-work, whereupon the drum will be permitted to drop back to its original position. In this movement of the drum with the shaft 2, it is clear that the cable 75 will be wound upon the segmental periphery of the drum, an upward pull being thus exerted upon the cable, and the latter transmitting such pull to the pitman 64 which will be forced with considerable power forward as it is swung upwardly and thus effect the forward movement of the plunger. As soon as the drum has been released, the plunger will quickly rebound. Preferably, a spring 83 is secured to the pitman 64 and extends along the upper edge thereof, said spring having a curved end which extends down between the links 69, as shown, the spring constituting a yielding seat for the link 72 j to ride on, and assisting in throwing the link back to position for the next forward stroke of the plunger. Manifestly, the link bars 66 of the pitman 64 are forced to move very rapidly in their initial forward and upward movement. This action, inconnection with the spring inv the cable 75 tends to throw the slotted link 72 back and down, and the roller 73 which rides in the slot of the links 72 will fall down, taking up quite a little of the stroke, which brings the plunger forward with increased power by having benefit of all, or nearly all the force of the plunger actuating mechanism. By the construction and arrangement of parts shown and described, it is clear that the spring cable 75 will, owing to its connection with the link bar 66 and pitman 64, bring the plunger pitman up and forward into the baler in a straight line.

The front door 0 f the ba'Zi'ng chamber and its operating means. (Sheets 1 and 7.)- The front wall of the baling chamber is formed by a door 84 which is swung from its upper edge, as at 85, and which is pivotally connected on its rear face half way between such edge and the opposite edge to one section 86 of a jointed brace plate 87. The rear edge of the section 86 of said brace plate is pivotally connected to a complemental section 88 between the front and rear edges of the latter, the parts being so arranged that when the rear edge of the section 88 overlaps and engages the section 86, with the two sections in a horizontal position at right angles to the door 84, the line of thrust against the rear face of the door 84 will be substantially coincident with the center of the plunger 51, and hence so long as the parts are in this position, the door will be prevented from opening, it being understood that the forward edge of the section 88 is pivotally connected to some portion of the framework, as at 89. After the bale has been completed, it is necessary for the door 84 to be released, so that the bale may be pushed forwardly from the baling chamber, and to accomplish the opening of the door 84, the lap joint of the sections 88 and 86 is broken by means of link rods 90 that are pivotally connected at their lower ends to the rear free edge of the section 88 and that are preferably adjustably connected at their upper ends to hell cranks 91, pivoted at 92. The upwardly project-
